Description
BACKGROUND
[0001] 1. Field of the Invention
[0002] The present invention relates to a base structure of an
electronic apparatus, and more particularly to a base structure of
an electronic apparatus that has an embedded power supply
device.
[0003] 2. Description of Related Art
[0004] In today's most electronic devices, a power supply device
such as a power adapter is an indispensable component. In addition
to voltage transformation, the power supply device usually has
other functions such as rectifying current with bridge rectifiers,
stabilizing voltage with capacitors, noise filtering, surge
protection with a fuse and etc.
[0005] Referring to FIG. 1, for example, for an electronic
apparatus 1 such as a LCD (liquid crystal display) or a notebook
computer, a power supply device 3 is usually additionally included.
The power supply device 3 can usually be adapted to use commercial
AC (alternative current) voltages in different countries, ranging
from 100V to 240V. When the power supply device 3 is connected to
an AC outlet by an electric cord 5, the commercial AC power source
will drive the power supply device 3 to work, upon which the power
supply device 3 can feed DC (direct current) voltage and current to
the electronic apparatus 1 and thereby drive the electronic
apparatus 1 to work.
[0006] A conventional power supply device of an electronic
apparatus, such as the power supply device 3 in FIG. 1, has an
electric cord 5 at a side thereof, and the electric cord 5 has a
power plug at an end thereof for being plugged into an AC outlet to
receive power. A DC cord 4 is connected to another side of the
power supply device 3 for connecting the power supply device 3 to
the electronic apparatus 1. In this way, the power supply device 3
is driven by the power coming from the AC outlet to provide DC
voltage and current to the electronic apparatus 1.
[0007] Generally speaking, the lengths of the electric cords 4 and
5 affect the dissipation of the electric power transmitted by the
electric cords. The longer the electric cords are, the more is the
electric power dissipated through transmission. In addition, longer
electric cords are more subject to physical damages such as being
bit by animals, rusty connection or cores caused by incomplete
insulating layer wrapping and etc.
[0008] With current technology, a regular power supply device
includes a circuit that transforms AC power into DC power and
therefore it is difficult to make the power supply device too small
without sacrificing the efficiency or the driving capability of the
power supply device. Thus, with the size of the power supply device
3 and the DC and AC power cords 4 and 5 connected thereto, it is
not convenient to collect the power supply device 3 or to carry it
along with the electronic apparatus 1.
[0009] It is understood that although winding the electric cords 4
and 5 may make collecting the power supply device 3 easier and make
the cords look better when winded, the winded cords may generate a
lot of heat caused by electromagnetic induction, which may melt the
cords, especially the insulating layer of the cords and result in
short circuit and danger. Thus it is desired to have an appropriate
space to place the power supply device 3 and the related electric
cords to eliminate the messy look of the cords and the safety
concerns thereof.
BRIEF SUMMARY
[0010] The present invention relates to an electronic apparatus
with an embedded power supply device, wherein a structure for
accommodating the power supply device is disposed on a base of the
electronic apparatus, and the power supply device is directly
mounted to the base of the electronic apparatus through connectors,
so as to decrease the possibility of the electric cords being
damaged when being exposed to the outside and improve the stability
of the power supply.
[0011] The present invention further relates to an electronic
apparatus with an embedded power supply device, wherein a structure
for accommodating the power supply device is disposed on a base of
the electronic apparatus, and the power supply device is directly
mounted to the base of the electronic apparatus through connectors,
so that an electric cord connecting the power supply device and the
electronic apparatus and transmitting DC power to the electronic
apparatus is no longer required, and thereby the electromagnetic
interference received by the electric cord can be eliminated and
the power supply device can provide more stable voltage and current
to the electronic apparatus. In addition, by reducing a DC electric
cord, it is more convenient to collect the power supply device and
the cost associated with the electric cord is saved.
[0012] A preferred embodiment of the present invention provides an
electronic apparatus with an embedded power supply device. The
electric apparatus includes a base, a power supply device, and an
accommodating structure disposed on the base for accommodating the
power supply device. A first connector is disposed on the base, and
a second connector is disposed on the power supply device. The
first connector is removably connected with the second connector.
In addition, the power supply device includes an electric cord for
receiving power from an external power source. When the first
connector is electrically connected to the second connector, the
power is provided to the electronic apparatus.
